Jewels are similar to Gems, except that instead of having predetermined magical abilities like a Gem, each Jewel
possesses random magic properties, allowing you to bestow a wide variety of magical abilities to your Socketed Item.
Rare Jewels can have up to four magical properties. Before inserting a Jewel, its magical properties
must be "identified" either by the use of a Scroll of Identify, or by a wise sage who can provide such a service.
